Weed seasons are the periods that start with planting your seeds and end with the tastiest, stickiest buds you can imagine. Indoor growing opened a world of possibilities for cultivators looking to enjoy rich harvests all year—but there’s clear value to taking your pot garden outdoors.
For one, it’s more affordable. The plants tend to be larger, too, gifting you with rich, fragrant flowers. It’s a bit trickier when you don’t have complete control over the environment, though.
Are you ready to take up the challenge and let your marijuana seeds develop as tall as they want with no constraints from your grow room?
Let’s dive into our weed seasons overview and help you get it right on the first try.
What are weed seasons?
Doesn’t the term ‘weed season’ fill your heart with joy? It communicates all the eagerness and affection outdoor growers experience while waiting for the ideal time to germinate their fresh pack of seeds.
As a novice grower, this could also be a source of dread. When should you plant? When is the harvest season for weed? There are endless questions, but the answers are pretty straightforward.
The outdoor cannabis growing season, specifically in the Northern Hemisphere, kicks off around early April. It stretches throughout the year, ending as late as mid-November in warmer parts of the country.
Since the weed seasons are region-dependent, there’s no one-size-fits-all answer to this question. Taking your seedlings to the dirt as soon as the weather is warm and sunny is ideal.
Timing and phases of growth for outdoor cannabis growers
Marijuana plants are annual, which means that they flower once a year. Outdoor cannabis growing season follows the same growth phases whether you’re a commercial cultivator or a two-pot novice.
Germination stage: Early spring
Those who like to buy weed seeds and grow cannabis from scratch need to start with germination. This step is the shortest and doesn’t leave a lot of room for error.
Growers usually pop their seeds after the last frost of that early spring. Once you do this, the ball starts rolling and there’s no stopping the weed season. A day or two later, you’re already transplanting the seedling to a soil container.
Those of you who enjoy taking genetically identical cuttings from the plants you know and love can skip the sprouting step altogether. ‘Tis the marijuana season right away with clones.
Seedling stage: Spring to early summer
Sprouting marks the beginning of the marijuana planting season. Your crop grows cotyledons and starts developing leaves more like the ones we know and love in the following two to three weeks.
Seedlings are especially sensitive to extreme environments, requiring moderation and stability to develop throughout the early weed season stages. As a rule of thumb, if you live in:
- Cold climates, take the containers outside only when there’s plenty of sunshine.
- Warm climates, give your cannabis seedlings some time indoors – up to a week should do. That way, they get strong and resilient against pests and mold.
Vegetative stage: Summer to early fall
Vegging is the marijuana growing season when growth starts to take off. Tiny, weak stems with few leaves develop lush foliage and get taller to reach the sun.
The cannabis vegetative stage is also the time to top and train your plants. Such practices encourage even light distribution, helping you manage plant height, and enhance each harvest by creating more bud sites.
Rules for this marijuana growing season include:
- Be generous with water and nutrients. Large roots require plenty of moisture, as well as additional nutes in scarce soil.
- Guard against pests. There’ll be nasty crawlers curious about your new bush. Go organic and spray religiously to avoid these issues.
- Watch for the males. Our feminized seeds are a go-to for most. If you’re going natural, get rid of the boys before they pollinate and wreck the harvest.
Plants enter the flowering stage once the longer nights start reaching around 12 hours in length.
Flowering stage: Fall
Cannabis flowering time is the most exciting of the weed seasons for most. Your weed crop dedicates all its energy to producing buds, which happens in three stages:
- Flower initiation. White, hairy pistils show up while the growth slows down.
- Mid-flowering. These pistils take on the familiar shape, and the rest stops growing.
- Ripening. Cannabis blossoms fatten up and form a thick coat of trichomes.
Flowering cannabis needs less water and more phosphorus. Also, consider adding a support system, as the flowers could get too heavy for the branches in this marijuana season. Bamboo canes, strings, stakes, or plant yoyos all do the job.
Marijuana harvest season: mid to late fall
The cannabis harvest time is why you embarked on this journey, and it’s finally come. All you have to do now is learn when is harvesting season and the best ways to do it.
The bush displays telltale signs that it’s entered the weed trimming season. Apart from the buds turning amber, the trichomes exhibit a deep, milky white hue to show you it’s marijuana harvest season.
If you’re the careful type, wait until the leaves start yellowing and curling. At that point, you’ve hit the best season for harvesting marijuana. You can’t get anything more out of your plant except for the sweet, sticky blossoms.
How does your environment affect the weed growing season?
Where you live has a massive impact on your planting schedule, marijuana harvest season, and everything in between. Timing is everything for going au naturel.
In general, western and southern regions of the US are warmer than their northern and eastern counterparts. It depends on the state, its mountains and how near they are to the oceans, but as a rule:
- Eastern and northen parts have harsh, snowy winters and mild summers, which makes the growing season shorter.
- Western and southern parts enjoy longer but scorching summers with longer periods amicable to growth.
These are handy generalizations, but you’ll have to get specific. Acknowledge, study, and rely on the weather in your locality. Different regions, even in the same general climate belt, have diverse environmental conditions.
Answer the following questions for your weed seasons:
- Temperature—what’s it like in general? Are the day-night shifts severe?
- Rainfall—how frequent and how heavy is it? How long does it usually last?
- Altitude—what’s the air quality around there? Is it moist or dry?
- Wind—how often does it blow? Do you experience light breeze or powerful gusts?
You can rest a bit easier if the weather is mild and stable. Those in volatile zones might have to think of plans B, C, and D and adapt their gardening efforts.
Do different strains have different growing seasons?
There’s a massive difference between photoperiod and autoflowering seeds.
- Outdoor photoperiods are highly dependent on the weed seasons. For instance, Diesel needs a lot of sunshine and finishes growing only in late October.
- Autos flower automatically without requiring a change in the light schedule. Take Lemon as an example — it’ll flower in around eight weeks regardless of the season.
Apart from that, strain genetics play a massive role in the marijuana growing seasons. Different strains take varying amounts of time to flower, with some swift cultivars like Carmen x Durban Poison blossoming in six to eight weeks, while slower varieties like OG Kush x Amnesia needing ten to twelve weeks.
This generalization could help:
- Indica-dominants such as Sweet Tooth are shorter and faster to flower.
- Sativa-dominants such as Mexican Haze are slow to mature into their imposing full stature.
Can cultivation techniques impact the weed growing season?
Cultivation techniques and strategies can all affect the growing season for marijuana.
If you’re stealth-growing or strapped for space, you’ll want to germinate your seeds later and keep your weed season short. If your state caps the number of containers, extend it to get the wealthiest possible harvest from each branch.
Other than that, these approaches can modify the speed at which your seedlings reach maturity:
- Topping—the plant undergoes some stress, making it necessary to prolong the vegging part of your marijuana growing season.
- Sea of green—quicker harvests without reduced output come with this low-stress training method.
- Monster cropping—this fun system requires some indoor equipment at one point or another. One container has to return to vegging while the other blossoms.
Top tips for your outdoor cannabis grow
Learning how to grow cannabis outdoors is challenging but massively rewarding once you master the basics. Weed seasons are essential, and on that note, let’s end with our top topical tips for growers.
Choose the ideal growing space
You might have a balcony or an entire farm ready to be covered in green throughout the outdoor marijuana growing season. In either case, picking the right spot is vital, and it’ll spare damage control in the long run.
Choose a location that’s:
- Accessible and easy to reach for all your gardening tasks
- Sunny—the lighter, the better
- Breezy but not windy to ensure ventilation but avoid blast stress
If you’re planting straight into the ground, check and amend the soil, too. Add an anti-pest fence or companions to help keep the bugs away — they’re among the worst enemies for those looking to take advantage of the outdoor marijuana growing season.
Track your progress
An intuitive green thumb is fantastic, but practice makes perfect.
A grow journal lets you track your cultivation efforts and note the weed season phases you struggle with the most. You’ll become more mindful of these issues and a better parent to your cannabis babies in time.

Water and nourish your cannabis bushes
Marijuana bushes react to external conditions. They’ll stop developing if they’re unsure when the next meal is coming, putting a rapid, unexpected stop to the joyful weed season.
Nutrients aren’t always necessary, but they can help. Find the best nute solution for the strain and take it slow to avoid toxicity.
When it comes to watering, you’ll have to play it by ear. In essence, every plant needs moisture to thrive. Watch for signs of over and underwatering and use pure, pH-neutral aqua.
Don’t bite off more than you can chew
If you’re an absolute newbie, don’t start a cannabis seed 12-pack at once. Sure, you might miss the weed season for the ones you don’t germinate, but messing up an entire costly harvest is an even worse scenario.
Start slow and work your way up – each subsequent yield will be more fruitful than the one before it. Supplement with simple autos or indoor grows if you find that your outdoor strains produce too little for your needs.
